General Zootechnics and Genetic Improvement
A.Y. 2020/2021
Learning objectives
The course aims to provide the principles of genetics applied to domestic animals. Aspects related to mendelian, population and quantitative genetics will be discussed. The topics related to molecular genetics will be developed with specific application to diagnostics applied to livestock production and genomic selection. The course also provides the principles of genetic improvement applied to livestock production pinpointing to the molecular genetics and genomics tools available today in livestock breeding. Information on ongoing selection programs in the main livestock populations of the national territory will be provided. The principles of bioethics applied to animal production will also be treated, with specific reference to the genomic and reproductive technologies available today in domestic animals.
Expected learning outcomes
Students will be able to implement a genetic improvement program in a dairy cattle farm using the tools available online for the choice of bulls. They will also have acquired the basic principle for a critical discussion on aspects related to animal breeding and farming.

Course syllabus and organization
Single session
Responsible
Lesson period
Second semester
Lectures will be held on the Microsoft Teams platform, even for those provided in person, and can be followed both in synchronous on the basis of the first scheduled lectures and in asynchronous because they will be recorded and left available to students on the same platform. Exams, if it is not possible to attend the classroom, will be performed orally through the Microsoft Teams platform.
Prerequisites for admission
No prerequisite
Assessment methods and Criteria
The exam will consist into 1 written test of 2 hours duration
Brief description of the test procedures:
Open and multiple-choice exercises and questions
The final report of the practical labs must be enclosed to the written evaluation and will contribute to grade the final exam
The final score will be determined by 50% of emphasis to the written test and 50% to the practical labs report.
